This comes from our own plant, not a trading desk. We do not have an office in your city and we will not invent one. What we can give you is factory pricing, consistent material and a technical answer before you commit.
01 / What it is
The material, and what it actually does on a Sao Paulo job
A layered curtain with a mass loaded vinyl core, used where an opening has to stay an opening. It is the answer for a doorway, a stage, a partition that must move, not a substitute for a wall.
Work reaching us from Sao Paulo is mostly corporate towers, apartments, restaurants, hotels, clinics, studios, schools.
Concrete frame with block infill and hard floors. Apartment towers share slabs and walls, and impact noise between floors is the common complaint.
- Full height with return Curtain taken floor to soffit with a side return and an overlap, because the gap is what leaks, not the fabric.
- Track with a seal Ceiling track plus a floor seal or drape, so the perimeter is closed when it is drawn.
- Double layer at a doorway Two curtains with an air gap where a single layer will not reach the target.
- What it will not do A curtain is only as good as its perimeter. Hung short, hung flat against a frame, or with a gap at the side, it will measure nothing like the figure on the sheet.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for soundproof curtains are on the main product page. This page covers what that means for a project in Sao Paulo.
02 / Specification sheet
One specification sheet, the same in every market
The specification below is the same everywhere we supply, because a specification that changed by city would not be a specification. What changes is which grade and build-up is the right buy, and that is what the rest of this page is about.
- Standard5.5 kg per sq m. Openings, stages, temporary partitions

Where a consultant is already engaged on a Sao Paulo project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
03 / Local conditions
What decides the build-up in Sao Paulo
- Towers block, interiors ring
Concrete frames handle airborne transfer. The complaint is nearly always that the room itself is too live.
- Traffic and helicopters
Street noise and rotor noise reach upper floors through glazing rather than structure, so the facade is where the money goes.
- Impact between apartments
Hard floors over slabs pass footfall down. The underlay has to go in before the finish, not after the complaint.
- Santos, then the climb inland
The port leg and the road leg are separate costs and separate time. We quote both rather than one.
- The housing stock
Concrete frame with block infill and hard floors. Apartment towers share slabs and walls, and impact noise between floors is the common complaint.
- The studio and content scene
A deep music and production culture works out of rooms inside apartment blocks and commercial floors.
Architects working in Sao Paulo usually need the build-up before the product. We will draw the section and mark what does the work. See how we support architects.
04 / Conditions
Why the climate in Sao Paulo changes the material, not the target
Sao Paulo is warm and humid through most of the year, with a long wet season, and that narrows the sensible material list before acoustics is even discussed.
Humidity is the deciding factor. PET felt does not absorb moisture, shed fibre or feed mould, which is why it outlasts fabric-wrapped mineral wool in this climate. Wood wool and timber need a ventilated cavity behind them.
The risk we design against here is mould, sagging fabric finishes and swelling in timber.
If the visual is fixed and the room still has to perform, that is a solvable problem and a conversation worth having early. See how we work with interior designers.
05 / Getting it there
How material reaches a Sao Paulo site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Santos, then road up to Sao Paulo |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Santos |
| Packing | Rolled and bagged with track and fixings listed separately. |
| Lead time | Made to size. Confirmed at quote. |
Standard items dispatch in 4 to 7 working days. The sea leg from India is long, so plan the full door to door window into the programme. We give real dates, not optimistic ones.
Sea freight into Santos, then road up to Sao Paulo. Air freight for samples and urgent quantities.
The same 5 piece minimum applies on export.
| Any size | 5 pieces |
|---|
Curtains are made to size, so the minimum is counted in pieces rather than area.

What we will tell you that a reseller will not
-
The wrong product for the problem
A curtain is only as good as its perimeter. Hung short, hung flat against a frame, or with a gap at the side, it will measure nothing like the figure on the sheet. We quote the detail, not just the fabric.
-
Coverage bought instead of a target
Lining every surface is a purchase, not a result. We would rather calculate the area against a reverberation target and sell you less of it.

Suppliers who imply a Sao Paulo presence
Ask any supplier where the material is made and who carries the warranty. We make it at Palwal in Haryana and we say so on every page, including this one.
Sao Paulo: questions we are actually asked
Do you manufacture soundproof curtains in Sao Paulo?
No, and we will not say otherwise. We manufacture at our own plant at Palwal in Haryana, India, and supply into Sao Paulo as the manufacturer rather than through a dealer. Made at our own plant in India and shipped into Santos, then road up to the city, with both legs quoted separately. You buy at factory prices with one consistent batch across the order.
What do you look at first on a Sao Paulo enquiry?
Concrete frames handle airborne transfer. The complaint is nearly always that the room itself is too live. Street noise and rotor noise reach upper floors through glazing rather than structure, so the facade is where the money goes. Those two things move the build-up far more than the panel figure does.
Does Sao Paulo weather shorten the life of this material?
Sao Paulo is warm and humid through most of the year, with a long wet season. Humidity is the deciding factor. PET felt does not absorb moisture, shed fibre or feed mould, which is why it outlasts fabric-wrapped mineral wool in this climate. Wood wool and timber need a ventilated cavity behind them. The failure we design against here is mould, sagging fabric finishes and swelling in timber.
How quickly can material reach a site in Sao Paulo?
ships from: Palwal, Haryana, India, arrives at: Santos, then road up to Sao Paulo, dispatch: 4 to 7 working days. Standard items dispatch in 4 to 7 working days. The sea leg from India is long, so plan the full door to door window into the programme. We give real dates, not optimistic ones.
Where do soundproof curtains fail to help?
A curtain is only as good as its perimeter. Hung short, hung flat against a frame, or with a gap at the side, it will measure nothing like the figure on the sheet. We quote the detail, not just the fabric.
How is the order packed and what is the minimum?
The same 5 piece minimum applies on export. Any size, 5 pieces. Curtains are made to size, so the minimum is counted in pieces rather than area. Rolled and bagged with track and fixings listed separately.

Drawings in, BOQ and a delivered date out
One drawing gets you a proper answer. Build-up, quantities, a delivered date, and an honest note on anything we think is the wrong approach.
